} Have you been trying double-[[ and triple-[[[ pairings? That is
} the normal way to pass literal "[" around and used widely
} within m4/autoconf. It is needed for such simple things as
} passing sed-char-ranges around (AC_X([sed -e `/[[0-9]].......)
} 
} 
It doesn't seem to work either. Here's what I get:

  --with-dmalloc=DIR  Use dmalloc memory debugging aid [default=no]
  --with-zlib=DIR     Use GNU zlib compression [default=yes]
  --with-ssl=LIB      Use the SSL library [default=no]
  --with-gass=DIR     Use the GASS library [default=no]
  --with-srb=DIR      Use the SRB Library [default=no]
  --with-pthread=DIR  Use the Pthreads library [default=no]

You can't see it, but the spacing is off in there. (The descriptions are
too close to the --with-* flags). The same thing happens if I use [[[.

I should mention that I'm using 2.53, so this may be a known deficiency
or something...not sure.
